A new Quinnipiac poll finds that instead of being the nation's hottest politician-which he was in January--he now ranks ninth.

The poll ranks people with a thermometer, and Christie, hurt by the George Washington Bridge closing controversy, is down to a 45.2 degree mean. He had been at a 55.5 degree mean.

Top rank now goes to Sen. Elizabeth Warren, D-Mass., at 48.6 degrees, but the poll adds that 46 percent don't know enough about her to have an opinion.

Second is former Secretary of State Hillary Clinton followed by House Budget Committee Chairman Paul Ryan, R-Wis, Louisiana Gov. Bobby Jindal and Wisconsin Gov. Scott Walker. Both are Republicans, and all four are mentioned as possible 2016 presidential candidates.
